What Does the Boiler Mean and How Does It Work?

Before we talk about gas boilers and oil boilers, it would make the most sense to start with the basics and get an idea of ​​how a boiler works and what it is. Even if you have an idea of ​​what a boiler is, we must make sure it's the right idea.

A boiler is a part of the heating system that is responsible for heating the house by boiling water and turning that water into steam. The water heated by the boiler is light, inexpensive, and extremely safe, and it can carry the heat wherever it needs to go. Since water vapor is many times lighter than air, it does not need to spend a lot of energy to move. Also, boilers are as efficient as they are amazing. Here's why a boiler is so great:


What is a Gas Boiler and How Does It Work?

There are many different types of gas boilers, but the logic of gas boilers is the same, regardless of the type of production or model. Gas boilers are responsible for heating your home using gas. A gas boiler may choose the direct mains route or an LPG cylinder route to have gas. Which one to choose depends on the construction and model of the gas boiler.

The gas boiler you use must produce hot water directed to your central heating system and radiators to adjust the temperature of your home according to your wishes and needs. This boiler can operate directly through a boiler connected to taps and showers, or the hot water you obtain will be transported to a separate water tank and cylinder depending on the model and type of boiler you have (i.e., system or heat type gas boilers).

When you turn on the heating feature of your gas boiler, hot water is first pushed to each radiator in the gas boiler, then the circulation in the radiators in this gas boiler must be continuous or close to constant. Even if your gas boiler needs to occasionally add pressure to its radiators, the same water can be used repeatedly. Even if the water used will have lost most of its heat when it passes through all the radiators, it will regain its old temperature inside the boiler before re-entering the same circulation. You can also understand whether your central heating is on by using the thermostat on your gas boiler, which helps keep the temperature of the house almost constant within a few degrees on either side of the temperature you have chosen, and if it is not, you can turn on the central heating with the help of this thermostat.


What are the Purposes of the Gas Boiler?

Although the primary purpose of gas boilers is to heat the house, the secondary purpose of these boilers is to heat water. Gas boilers, which realize their second purpose in the same way as their first purpose of realizing central heating, achieve both purposes by pumping heated water above the flame and have two ways to achieve this. The first form is to have hot water for immediate use, as in combi boilers, while the second is to heat the water in the tank, such as a system boiler or a heating boiler. Whatever method is used, this water heated by flame is not the water coming out of the tap, this water is only used as a medium to heat the water you use.


How Does a Gas Boiler Heat Water?

A gas boiler has several different components, including the gas burner, heat exchanger, and flue. Although the general purpose of all these components is to heat your home and the water used in your home, they all have different functions. The so-called primary components are the gas burner and the heat exchanger. A gas boiler including these components works like this:


Do Gas Boilers Require Electricity to Work?

Although the general purpose of gas boilers is to heat water and keep your home warm, although they also use gas these boilers, they still need electrical power to operate. While this may sound unusual, the intended use of electricity is only to help certain items in your central heating systems operate and function. In addition, since even the valve that opens to provide gas flow to the combustion chamber works with electricity, it is quite normal to think that application-controlled smart boilers will also work with electricity.


Why You Should and Shouldn't Choose Gas Boilers?

For your gas boilers to have gas when you choose gas boilers, they must be connected by a heating systems specialist to a gas line that also serves the rest of your neighborhood. When you need to heat your home or heat the water in your home, natural gas is pumped directly into your home gas boiler and used as fuel to heat your home or water in your home.

What Does Oil Boiler Mean?

You want to find the best oil boiler for your home, but if you don't know how to find out which oil boiler is good or not, first you need to find out what type of heating system your home heating system is. More than eighty-five percent of homes in the UK use gas boilers for central heating and hot water. Although it seems extremely unnecessary to use oil boilers, since seventeen out of twenty people are gas boilers, there are regions where oil boilers are also used. Oil boilers are especially ideal for homes that do not have access to municipal gas networks, and oil boilers are still frequently used for central heating and hot water needs of remote and rural homes.

Oil boilers, whose popularity has decreased over the years, can still be sold and used cheaper than heating systems working with electricity and LPG. Mechanically speaking, the main difference between oil boilers and gas boilers is that they both store the fuel differently. So gas boilers and oil boilers work the same way.

We have already mentioned why people living in remote areas do not have access to gas boilers, but let's talk about it briefly. The most important reason why gas boilers are not used in remote or rural areas is that the fuel used by gas boilers comes from the national network, oil boilers are used in these regions because there is no access to this national network in remote areas. If you want to use an oil boiler, it will be sufficient to have an oil tank for these boilers that will be located in a large place such as a garden or basement. However, you should not forget that this oil tank should be changed regularly.


Why You Should and Shouldn't Choose an Oil Boiler for Your Home?

We mentioned that the most important difference between oil boilers and gas boilers is storage. If you are going to use an oil-based boiler, you need to have an oil tank in your home, garden, or warehouse. Now let's look at why you should and shouldn't choose an oil boiler for your home.
